util.argparse: Rename kv_params to bool_params, remove support for arbitrary values We have value_params now, which has overlapping behaviour and support for '--foo bar' as well as '--foo=bar' (only the latter syntax is supported by kv_params). The remaining unique property of kv_params is that when used without a value, i.e. '--foo' then it defaults to boolean true, and when used as '--no-foo' it defaults to boolean false. This is a useful thing that value_params don't do. So this commit officially renames kv_params to bool_params (kv_params is still allowed for now, for some backwards compatibility). Breaking change though: if any kv_params expected a value, it will no longer work (--foo=bar will not work). In this case the param should be moved to value_params.
